A method and apparatuses may be provided for detection, tracking, and classification of one or more land, maritime, or airborne objects using a real-aperture radar mounted on a parasail airborne platform. Both wide-area and localized radar surveillance can be provided, and the radar can be either a non-coherent radar or coherent radar. A method and apparatus may use a low-cost, rotating, single-beam, non-coherent, X-band radar that is mounted on an unmanned powered parasail and operated remotely like an Unattended Airborne System (UAS). The parasail, which may be expendable or recoverable, manned or unmanned, powered or unpowered, may have a low operational cost, can carry a heavy payload, stay on station for a long time, circle or move to a specified location for surveillance, operate at an optimal altitude and look-angle, and automatically cue or manually steer an EO/IR camera to a target of interest for classification and identification.
Legal claims defining the scope of protection, as filed with the USPTO.
1. An airborne platform comprising: an untethered wind-sail; a propulsion system; a radar configured to detect at least one target; and an imaging system configured to classify the at least one target, wherein the imaging system is cued to classify the at least one target by the radar.
2. The airborne platform of claim 1 , further comprising: a computing device to collect radar data from the radar.
3. The airborne platform of claim 1 , further comprising: a radio device configured to transmit data associated with the at least one target.
4. The airborne platform of claim 1 , wherein the radar comprises a non-coherent radar and wherein the airborne platform comprises a processor to process data obtained by the radar to determine a track of the at least one target.
5. The airborne platform of claim 1 , further comprising a processor to process data obtained by the radar to determine a track of the at least one target.
6. The airborne platform of claim 5 , further comprising: a display device configured to display the track of the at least one target.
7. The airborne platform of claim 5 , further comprising a radio configured to transmit the at least one track to a computing device for display by the computing device.
8. The airborne platform of claim 1 , further comprising a storage device configured to store data collected by the radar.
9. The airborne platform of claim 1 , further comprising a plurality of sensors and wherein the storage device stores data captured by the plurality of sensors.
10. The airborne platform of claim 1 , further comprising: a plurality of sensors; and a display device configured to combine and display data captured by at least two of the plurality sensors.
11. The airborne platform of claim 1 , wherein the imaging system includes a camera.
12. The airborne platform of claim 11 , wherein the camera is configured to respond to a frequency range based on a type of target requested to detect.
13. The airborne platform of claim 12 , wherein the camera is a hyperspectral camera.
14. The airborne platform of claim 1 , wherein the imaging system includes an infrared sensor.
15. The airborne platform of claim 1 , wherein the at least one target includes a person.
16. The airborne platform of claim 1 , wherein the at least one target includes a small boat.
17. The airborne platform of claim 1 , wherein the radar is a coherent radar.
18. The airborne platform of claim 1 wherein the propulsion system is configured to move the airborne platform in response to commands received at a radio device of the airborne platform.
